I have this. Plantar fascitis. I've been googling and talking to fellow walkers with it and more googling...
I will be doing the stretches, icing and resting my left foot for a week or so.
I jokingly told my DD it's her fault. I've had issues with my left foot ever since being pregnant with her. She had all her baby weight on my left side when I carried her and my left foot would often go numb. I could always tell afterwards if I was starting to put on too much weight, my left foot would start to be sore and go numb.
But this? Probably too many miles on last year's shoes. I wanted to wait until my clinic on May 15th to get new shoes, and I may have hurt my foot with worn out shoes.
Any other ideas on what I can do, please let me know.
